SI ("SYSTÈME INTERNATIONALE) UNITS The fundamental units of the "metric system" are: the kilogram (kg) for mass, ç the second (s) for time, ç the meter (m) for length, and ç the ampere (A) for electric current. ç In addition to the basic units of SI, multiples and submultiples can be formed used metric prefixes such as M (for mega) for 1,000,000 or (for micron) for 0.000001. The prefixes and . their symbols are listed below. The most common ones, the ones you should know, are given in boldface. atto (a) 10 femto (f) 10 œœ  18 15 pico (p) 10 œ 12 nano (n) 10 micro ( ) 10 milli (m) 10 œ 96 3 .
